Intellectual property law protects brands, creative works, inventions and product designs. In India, the main statutes are the Trade Marks Act 1999, the Copyright Act 1957, the Patents Act 1970 and the Designs Act 2000. Chennai has branch offices of the Trade Marks Registry and the Patent Office, and the Geographical Indications Registry is based in the city.
Which type of IP protects what?
Choosing the right protection depends on what you want to stop others from copying:
- Trademark — brand names, logos, slogans and other marks that identify your goods or services.
- Copyright — original literary, artistic, musical and software works; protection arises on creation, while registration helps as evidence.
- Patent — new inventions that involve an inventive step and are capable of industrial application.
- Design — the visual shape, configuration or ornamentation of a product.
- Geographical indication — products linked to a specific region, such as many Tamil Nadu handlooms and foods.
Protecting a brand: trademark first
For most small and growing businesses, trademark registration is the first IP step. A clearance search before adoption reduces the risk of objections or conflicts later.
Our separate trademark registration page explains the filing process step by step.
Handling infringement and IP notices
If someone copies your brand or content — or you receive a cease-and-desist notice — the options include a reasoned reply, negotiation, opposition or rectification proceedings before the Registry, and civil suits seeking injunctions and damages.
IP suits of specified value are treated as commercial disputes. The Madras High Court has an Intellectual Property Division that hears many IP matters.
IP in contracts and employment
Ownership of IP created by employees, freelancers and agencies should be addressed in writing. Assignment and licence agreements, non-disclosure agreements and clear IP clauses in vendor contracts prevent disputes later.
Common questions
Do I need to register copyright to own it?
No. Copyright exists automatically once an original work is created. Registration with the Copyright Office is optional but provides useful prima facie evidence in a dispute.
How long does a trademark registration last in India?
A registered trademark is valid for ten years from the application date and can be renewed for successive ten-year periods.
What should I do if I receive a trademark infringement notice?
Do not ignore it, and avoid replying informally. Preserve your records of first use and get the notice reviewed so that a measured response can be prepared.
